Umm... They actually use DLT tech which spread across multiple sites, therefore it is decentralized. I may not understand your concern but here is a source ('https://themerkle.com/distributed-ledger-technology-vs-blockchain-technology/') and I also don't see the counterparty risk you are mentioning, they use multi-key verification, therefore removing the idea of trust in the transaction and making the transaction much less risky. Also, let's not forget that varying levels of counterparty risk apply in all financial transactions. @vato
